Which one of the following is an example of homogeneous catalysis ?

Options

A. Manufacture of sulphuric acid by cotact process
B. Manufacutre of ammonia by Haber's proess
C. Hydrolysis of surcose in the presence of dilute hydrochloric acid
D. Hydrogenation of oil

Answer

C

Explanation

In homogenous catlysis, reactants and catalyst are in the phase
`underset(("Constant process"))(SO_(2)(g)+O_(2)(g))overset(Pt(s)) hArr SO_(3)(g)`
It is example of heterogeneous catalysis.
`N_(2)(g)+H_(2)(g)overset(Fe(s))hArr underset(("Haber's process"))(2NH_(3)(g))`
It is example o fheterogenous catalysis.
`C_(12)H_(22)O_(11)(aq)+H_(2)O(q)overset(HCI(aq)) hArr C_(6)H_(12)O_(6)+C_(6)H_(12)O_(6)`
It uis an example of homogenous catalysis.
`"Oil" (l) H_(2)(g) overset(("Hardening"))underset(Pt(s))rarr "fat"`
thus, it is also an example o9f heterogenous catalysis.
